AB  - BACKGROUND: Skin marker-based analysis of functional spinal movement is a 
      promising method for quantifying longitudinal effects of treatment interventions 
      in patients with spinal pathologies. However, observed day-to-day changes might 
      not necessarily be due to a treatment intervention, but can result from errors 
      related to soft tissue artifacts, marker placement inaccuracies or biological 
      day-to-day variability. RESEARCH QUESTION: How reliable are skin marker-derived 
      three-dimensional spinal kinematics during functional activities between two 
      separate measurement sessions? METHODS: Twenty healthy adults (11 females/9 
      males) were invited to a movement analysis laboratory for two visits separated by 
      7-10 days. At each visit, they performed various functional activities (i.e. 
      sitting, standing, walking, running, chair rising, box lifting and vertical 
      jumping), while marker trajectories were recorded using a skin marker-based 
      10-camera optical motion capture system and used to calculate sagittal and 
      frontal plane spinal curvature angles as well as transverse plane segmental 
      rotational angles in the lumbar and thoracic regions. Between-session reliability 
      for continuous data and discrete parameters was determined by analyzing 
      systematic errors using one sample T-tests as well as by calculating intraclass 
      correlation coefficients (ICCs) and minimal detectable changes (MDCs). RESULTS 
      AND SIGNIFICANCE: The analysis indicated high relative consistency for sagittal 
      plane curvature angles during all activities, but not for frontal and transverse 
      plane angles during walking and running. MDCs were mostly below 15 degrees , with 
      relative values ranging between 10 % and 750 %. This study provides important 
      information that can serve as a basis for researchers and clinicians aiming at 
      investigating longitudinal effects of treatment interventions on spinal motion 
      behavior in patients with spinal pathologies.
